World’s first H2- fueling station to be supplied from municipal wastewater  

By Gerald Ondrey |

Air Products (Lehigh Valley, Pa.; www.airproducts.com) today officially opened its newest California hydrogen fueling station drawing its feedstock from a very novel and sustainable source. Air Products is pumping hydrogen into fuel cell vehicles that is generated from the municipal wastewater-treatment plant at the Orange County Sanitation District (OCSD) in Fountain Valley. In addition to generating hydrogen, the project also creates electricity and heat from this renewable source. This technology application is uniquely the first in the world and opens significant opportunities for other biogas feedstock streams. Methane gas is created while the wastewater at the OCSD facility sits in holding tanks. This methane begins a clean-up process where the gas stream enters a purification system and then feeds into a fuel cell, built by FuelCell Energy, Inc. (Danbury, Conn.; www.fuelcellenergy.com), where it is reformed to hydrogen. In the fuel cell, clean electricity is produced for use at the OCSD facility, and the heat created could also be directed to several site uses. Excess hydrogen not converted to electricity leaves the unit and is further purified to make it vehicle grade for fuel cell automobile fueling via Air Products’…
